Abstract

Continuously cast slab serves as a billet for the production of high-quality plate and coiled stock for pipes. The initial quality of slab largely determines the ability to meet the requirements on surface quality, contamination with non-metallic inclusions, impact toughness, crack resistance in H2S-containing media, continuity, etc. The quality of continuously cast billet is formed at the stages of liquid steel treatment in the ladle, in the vacuum unit, in the ladle-furnace unit, in the intermediate ladle, and upon continuous casting. Thereby, the problems of ensuring the chemical composition within specified limits, the low content of harmful impurities (sulfur, phosphorus) and gases (nitrogen, hydrogen, oxygen), cleanliness from non-metallic inclusions, minimization of surface and internal defects of the slab, etc., are solved.
